680 SLI power requirements?

cburke82 · Jun 17, 2013

Is there any way I could run 680/770 SLI with a 750W PSU? LOL Im thinking this is a no in advance but just maybe.....

A quality 750W PSU, yes. A bad, terrible, or crappy PSU, no.

680 Yes, 770 no it would need an 850W. On top of that look at the number of conncetors.

Quality of the psu is a must.

So a Thermaltake 750W would that work?

Also I think I know the answer but would have a lower power PSU possibly damage the system with two cards or would it just shut down when the power needed was not available?

Nope. Thermaltake makes some of the crappiest PSUs I've ever seen. Go for XFX, Seasonic, Corsair, or Antec if you want SLI/XFire.

Thanatos Telos :

don't judge psu's by brand on the unit, decide on it based on whats in the unit. buying by brand can give you terrible choices at times. albeit thermaltake has a history of pretty meh units, for instance, if OP had a Thermaltake Toughpower DSi(new digital PSU) then it would totally work fine

to OP: a 680 SLI is has a recommendation of 800w(at least from realhardtechx) but generally power consumption is grossly exagerated. it should work fine depending on the exact power supply you are using and the rest of the systems components/clocks. and average typical load/max load
